Learn
belly-breathing (diaphragmatic breathing) techniques,
and practice them when you are not hyperventilating so that you can use the
techniques when you need them. People who hyperventilate usually take shallow
breaths, filling only their upper chest when they inhale.

Try
different relaxation techniques and see what works best for you. For more
information, see the topic
Stress Management.

Talk to friends, family
members, or a counselor to help you relieve anxiety. Keep a journal to help you
focus on your problems and find workable solutions.

Eat a healthy
mix of foods. Watch out for caffeine: drink less coffee, tea, and soda, and do
not eat as much chocolate. For more information, see the topic
Healthy Eating.

Exercise. Regular aerobic
exercise forces you to take full breaths and helps you to reduce anxiety that
contributes to hyperventilation. For more information, see the topic
Fitness.
